Description

Technical Field

[0001] The invention relates to the technical field of offshore construction, and in particular to a pile-sinking positioning frame structure. Background Art

[0002] In the construction of marine engineering and offshore structures, the jacket is an important structure supporting the platform. Its construction quality and efficiency are directly related to the safety and economy of the entire project. The jacket is usually constructed by the pile-first method, that is, the steel piles are constructed first. In this step, the precise positioning and verticality control of the steel piles are the key to ensure the stability of the jacket. In order to achieve this goal, the pile positioning frame is widely used in the construction process of steel piles.

[0003] The main function of the pile positioning frame structure is to guide and position the steel piles by setting guide cylinders to ensure that the steel piles can be accurately and vertically sunk into the seabed according to the design requirements. The number, spacing and diameter of the guide cylinders must match the spacing and pile diameter of the jacket steel piles to ensure the accuracy and efficiency of the construction. However, the existing pile positioning frame structures on the domestic market currently generally have a significant problem: the spacing of their guide cylinders is a fixed spacing type.

[0004] This means that each pile locator structure can only be used for a specific pile spacing. When encountering a jacket project with different pile spacings, it is necessary to select a suitable pile locator structure based on the specific pile spacing. In the actual operation process, for each new jacket project, if its pile spacing does not match the guide tube spacing of the existing pile locator structure, it is necessary to redesign and manufacture a new pile locator structure, and the pile locator structure needs to be transported from the construction site to the processing site, and then the guide tube is cut off at the processing site, and then welded to the pile locator structure at a set distance, and then the welded pile locator structure is transported from the factory to the construction site. This fixed spacing design not only limits the versatility and flexibility of the pile locator structure, but also increases the preparation time and cost before construction. Summary of the invention

[0005] The purpose of the invention is to provide a pile positioning frame structure. By improving the pile positioning frame structure, it can be flexibly adjusted according to different pile spacings, without the need to manufacture a new pile positioning frame structure separately for each project, thereby improving the versatility and flexibility of the pile positioning frame and reducing the preparation time and cost before steel pile construction.

[0006] To achieve the above-mentioned purpose, the present invention provides a pile driving positioning frame structure, including a guide cylinder, a supporting structure for supporting the guide cylinder, and a main structure with a square horizontal cross-section, the vertices of the square are fixedly connected to the supporting structure; the supporting structure encloses and defines at least one adjustment channel, the adjustment channel has a channel centerline that coincides with the extension line of the diagonal of the square, and the adjustment channel is provided with a plurality of installation positions along the extension direction of the channel centerline, the guide cylinder can be connected to different installation positions, and the center of the guide cylinder is always located on the adjustment centerline.

[0007] By adopting the technical solution of the present application, a pile positioning frame suitable for adjustable pile spacing is provided, and the guide tube spacing can be adjusted according to the change of the pile spacing of the steel piles of the conductor frame, so that one pile positioning frame structure can be suitable for a variety of pile spacings, thereby improving the scope of use of the pile positioning frame structure and saving the cost of project construction equipment.

[0008] Optionally, the support structure includes two support beams, and an adjustment channel is defined between the two support beams; each support beam is arranged parallel to the center line of the channel, and a plurality of limiting teeth arranged in sequence and spaced apart are provided in the extension direction of the support beam to define different installation positions; a plurality of protrusions are provided on the outer wall of the guide cylinder, and the protrusions can be inserted between two adjacent limiting teeth on the corresponding side and directly or indirectly pressed against the support beam.

[0009] In this embodiment, a plurality of spaced-apart limiting teeth are provided on the support beam to provide multiple optional installation positions for the guide cylinder, thereby allowing the user to easily adjust the position of the guide cylinder according to specific needs to adapt to different pile spacings. This design greatly improves the flexibility and adaptability of the pile positioning frame; in addition, the protrusions provided on the outer wall of the guide cylinder enable the guide cylinder to be firmly inserted and locked between two adjacent spaced-apart limiting teeth on the corresponding side, directly or indirectly pressed against the support beam, ensuring the stability and accuracy of the guide cylinder after adjustment.

[0010] Optionally, the limiting teeth extend in the vertical direction, and a spacing portion is defined between the two limiting teeth. In the process of inserting the protrusion into the spacing portion, a lifting device is first used to insert the guide cylinder along the diagonal direction from the outside of the support beam to the position between the two support beams. During the insertion process, ensure that the height of the protrusion is higher than the highest position of the limiting teeth; then, after the protrusion is vertically aligned with the corresponding spacing portion, the lifting device is used to lower the guide cylinder to insert the protrusion from top to bottom into the spacing portion.

[0011] Optionally, in order to facilitate plug-in, the mouth of the spacer where the protrusion is inserted is defined as a socket, and the portion of the socket surrounded by the top of the limiting tooth is chamfered, so that the spacer has a flared structure.

[0012] In this embodiment, the center position between two adjacent limiting teeth is an installation position, and those skilled in the art can adjust the spacing between each installation position by adjusting the center position between the two limiting teeth as needed.

[0013] Optionally, the side wall of the guide cylinder is fixedly provided with two cam groups in the same horizontal plane, and the two cam groups are symmetrically arranged relative to the center line of the channel to match the support beam on the corresponding side;

[0014] Each of the cam groups includes one or two cams, defining the guide cylinder to also have a reference line in the horizontal plane, the reference line passing through the center of the guide cylinder and perpendicular to the center line of the channel, and the two cams in the same cam group are symmetrically arranged relative to the reference line.

[0015] Optionally, in a horizontal plane, a direction perpendicular to the center line of the channel is defined as the width direction of the adjustment channel; in the width direction, the protrusion exceeds the outer tooth wall of the limiting tooth; the protrusion is also provided with a first limiting plate, and the first limiting plate is fixedly connected to the part of the protrusion located outside the limiting tooth; the first limiting plate is arranged on both sides of the protrusion and is used to abut against the outer tooth wall of the limiting tooth on the corresponding side in the width direction of the adjustment channel.

[0016] In a specific implementation process, when inserting the protrusion into the spacing portion from top to bottom, it is necessary to align the first limiting plate with the outer side wall of the limiting tooth in the vertical direction, and then use a lifting device to insert the protrusion into the spacing portion.

[0017] In this embodiment, the two convex groups fixed on the side wall of the guide cylinder are in the same horizontal plane, the two convex groups are located at the same elevation, and the two convex groups are symmetrically arranged relative to the center line of the channel. This design ensures that the guide cylinder can be evenly stressed after adjusting the spacing, and effectively prevents the deviation or tilt caused by uneven force on one side. At the same time, each convex group includes one or two protrusions, which can be accurately inserted between the limiting teeth of the corresponding side support beam to achieve stable locking. In particular, when the two protrusions of the same convex group are symmetrically arranged relative to a reference line passing through the center of the guide cylinder, the stability of the guide cylinder in the horizontal plane is further enhanced, and the positioning accuracy is improved. The symmetrical distribution of the two convex groups allows the guide cylinder to be easily aligned with the limiting teeth of the support beam during installation, without the need for complex adjustment and calibration steps, simplifying the installation process and reducing installation time.

[0018] Optionally, at least one of the protrusions in the same cam group is further provided with a second limiting plate parallel to the first limiting plate, the second limiting plate being arranged opposite to the first limiting plate in the width direction and being able to abut against the inner side wall of the limiting tooth. By providing the second limiting plate on the protrusion, the first limiting plate and the second limiting plate can form a stop for the limiting tooth on both sides of the limiting tooth, thus increasing the support of the limiting tooth on the guide cylinder, and further increasing the stability of the guide cylinder in the process of guiding the steel pile.

[0019] Optionally, a spacing portion is defined between two adjacent limiting teeth, and two latching protrusions in the same latching protrusion group are correspondingly adapted to two non-adjacent limiting protrusions; and the first limiting plate extends beyond the limiting teeth in the extension direction of the support beam.

[0020] Optionally, a connecting plate is further included, part of which is welded to the end face of the protrusion, and the other part is welded to the support beam. By providing the connecting plate, the guide cylinder and the support beam can be connected vertically, thereby preventing the guide cylinder and the support beam from accidentally disengaging vertically; in the actual operation process, if the installation position of the guide cylinder needs to be adjusted, the connecting plate can be cut off and re-welded to the new installation position. This processing method is relatively simple and convenient, and can also ensure the vertical connection strength between the guide cylinder and the support beam.

[0021] Optionally, a limit module is included, the limit module is welded to the top surface of the support beam, the limit module includes the limit tooth and a support frame, the bottom end of the support frame is welded to the top surface of the beam, and a plurality of limit teeth located on the same support beam are welded to the top of the support frame. Thus, the limit teeth can be processed in a modular manner, the limit accuracy of the limit teeth is ensured, and the difficulty of connecting the limit teeth to the support beam is reduced.

[0022] Optionally, the support beam further comprises an inner side wall of the beam, the inner side wall of the beam is arranged perpendicular to the top surface of the beam, and the inner side wall of the beam constitutes a wall portion of the adjustment channel;

[0025] The support frame consists of a horizontal plate arranged parallel to the top surface of the beam and two vertical plates perpendicular to the top surface of the beam. This design enables the support frame to fit more firmly on the beam structure, effectively dispersing and bearing loads from above or from the side, thereby improving the stability and bearing capacity of the overall structure.

[0026] Optionally, a welding plate is further provided between the top surface of the beam and the horizontal plate, the welding plate is parallel to the vertical plate and is located outside the vertical plate; a portion of the connecting plate is welded to the outer side wall of the welding plate. The method of separately providing a welding plate outside the position parallel to the vertical plate facilitates the welding of the connecting plate and the support frame, while avoiding the connection plate being directly welded to the vertical plate, which causes stress concentration on the local part of the vertical plate.

[0027] Optionally, the outer side of the transverse plate exceeds the welding plate, and at least part of the connecting plate is supported between the lower plate wall of the transverse plate and the top surface of the beam. By extending the connecting plate to the lower side of the transverse plate and welding it to the lower plate wall of the transverse plate, the support frame can further limit the connecting plate in the height direction, further improving the connection strength of the guide cylinder and the support beam in the vertical direction.

[0028] Optionally, a spacer is defined between two adjacent limit teeth; and the device also includes a reinforcing rib plate, which is perpendicular to the vertical plate and connected between the top surface of the beam and the lower plate wall; the reinforcing rib plate is projected vertically to form a first projection, the spacer is projected to form a second projection, the limit teeth are projected to form a third projection, and the welding plate is projected to form a fourth projection; the first projection at least partially overlaps with the third projection, and the third projection at least partially overlaps with the fourth projection.

[0029] In this way, the reinforcing rib plate further strengthens the part where the limiting teeth are set, thereby increasing the connection strength between the limiting teeth and the support beam; at the same time, the welding plate further strengthens the spacer part where the protrusion is set; after the protrusion is connected to the support beam, the connecting plate is parallel to each reinforcing rib, which can also further improve the connection strength between the protrusion and the support beam.

[0030] Optionally, the guide cylinder includes a cylinder body and a bell mouth arranged on the cylinder body, and the two cam groups located on the same plane are arranged at the position where the cylinder body and the bell mouth are connected.

In the horizontal direction, the wall of the bell mouth is in an inclined state, that is, it gradually tilts outward from the low point where the tube body is located to the high point. The bell mouth and the protrusion are projected vertically respectively, and the projection range of the bell mouth will cover the projection range of the protrusion. By connecting the upper surface of the protrusion to the outer wall of the bell mouth through the first reinforcing plate, the connection part between the protrusion and the guide tube can be further strengthened.

[0033] Optionally, the main structure further comprises a cross brace connected between two adjacent legs; the cross brace is welded to the portion of the leg where the transition portion is provided. By also providing the cross brace at the portion where the transition portion is connected to the leg, the portion of the leg connected to the transition portion is further strengthened by the cross brace to prevent the leg from buckling.

[0034] Optionally, a first reinforcing beam is further included, one end of the first reinforcing beam is welded to the transition portion, and the other end is welded to the cross brace; the first reinforcing beam and the cross brace are located in the same plane. Thus, the cross beam is further reinforced by the first reinforcing beam, thereby increasing the connection strength between the transition portion and the cross brace.

[0035] Optionally, a second reinforcing beam is further included, the second reinforcing beam is connected between two adjacent cross braces, and the second reinforcing beam, the first reinforcing beam and the cross brace are located in the same plane, thereby further improving the horizontal support of the cross beam to the brace leg.

By providing the transition part, the two support beams can be fixedly connected to the vertically extending support leg, thereby realizing a rigid connection between the support beam and the main structure.

[0037] Optionally, the transition part further includes a reinforcement block, the reinforcement block is abutted between the first beam and the second beam, and the reinforcement block, the two first reinforcement beams, and the second reinforcement beam form a closed structure, thereby further providing stable support for the transition part in the horizontal direction.

DETAILED DESCRIPTION

[0053] The main function of the pile sinking positioning frame structure is to guide and position the steel piles by setting the guide cylinder to ensure that the steel piles can sink accurately and vertically into the seabed according to the design requirements. Specifically, the specific guiding process of the steel piles includes: Step 1, determine the pile position: At the construction site, use a total station, laser positioning device or GPS and other high-precision positioning equipment to determine the exact position of each pile according to the design drawings. Step 2, install the positioning frame: install the positioning frame on the determined pile position. The positioning frame is usually made of solid steel and has sufficient strength and stability to ensure that it does not deviate or overturn during the pile sinking process. Step 3, adjust the positioning frame: adjust the positioning frame accurately to the position corresponding to the pile position through means such as hydraulic systems. This step requires the operator to fine-tune the equipment on the working platform according to the measurement data of the positioning equipment to ensure the accuracy of the positioning frame. Step 4, guide the steel pile: During the pile sinking process, the positioning frame plays the role of guiding the steel pile. Driven by a vibrating hammer or other pile sinking equipment, the steel pile gradually sinks along the inner wall of the positioning frame until it meets the design requirements.

[0054] In the process of guiding and positioning steel piles, the number, spacing and diameter of the guide tubes must match the spacing and pile diameter of the jacket steel piles to ensure the accuracy and efficiency of the construction. However, the existing pile positioning frame structures on the domestic market generally have a significant problem: the spacing of their guide tubes is fixed.

[0055] This means that each pile locator structure can only be used for a specific pile spacing. When encountering a jacket project with different pile spacings, it is necessary to select a suitable pile locator structure based on the specific pile spacing. In the actual operation process, for each new jacket project, if its pile spacing does not match the guide tube spacing of the existing pile locator structure, it is necessary to redesign and manufacture a new pile locator structure, and the pile locator structure needs to be transported from the construction site to the processing site. After the guide tube is cut off at the processing site, it is welded to the pile locator structure at a set distance, and then the welded pile locator structure is transported from the factory to the construction site. This fixed spacing design not only limits the versatility and flexibility of the pile locator structure, but also increases the preparation time and cost before construction.

[0056] The present invention provides a pile positioning frame structure. By improving the pile positioning frame structure, the pile positioning frame structure can be flexibly adjusted according to different pile spacings, and there is no need to manufacture a new pile positioning frame structure separately for each project. The versatility and flexibility of the pile positioning frame are improved, and the preparation time and cost before steel pile construction are reduced.

[0057] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0058] The directions "up" and "down" in this article refer to the side of the pile positioning frame structure pointing to the seabed when it is in normal working condition, with the side pointing to the seabed being down and the opposite being up.

[0059] Relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0060] Please refer to Figures 1 to 9 , Figure 1 1 is a schematic structural diagram of a pile driving and positioning frame structure in an embodiment of the present invention;

[0061] Figure 2 yes Figure 1 A partial structural enlarged schematic diagram showing a state where the guide cylinder is not installed; Figure 3 yes Figure 1 A partial structural enlarged schematic diagram showing a state where a guide cylinder is installed; Figure 4 yes Figure 2A partial structural enlarged schematic diagram; Figure 5 yes Figure 3 A partial structural enlarged schematic diagram; Figure 6 2 is a schematic structural diagram of a guide tube of a pile sinking positioning frame structure in an embodiment of the present invention; Figure 7 yes Figure 6 A partial structural enlarged schematic diagram; Figure 8 yes Figure 3 A top view of Fig. 9 yes Figure 1 Top view of the .

[0062] The present invention provides a pile driving positioning frame structure, comprising a guide cylinder 2, a support structure 3 for supporting the guide cylinder 2, and a main structure 1 with a square horizontal section, wherein the vertices of the square are fixedly connected to the support structure 3.

[0063] Among them, the support structure 3 supports the guide cylinder 2 in the direction of its gravity, and the connection position between the support structure 3 and the guide cylinder 2 is not limited to the bottom of the guide cylinder 2, but can also be the side of the guide cylinder 2 and / or the top of the guide cylinder 2. The cross-section of the main structure 1 in the horizontal plane is a square, but its cross-section in the vertical plane can be a trapezoid, a rectangle, a square or a triangle. The specific shape of the cross-section of the main structure 1 in the vertical plane is not limited here. The guide cylinder 2 is provided with a guide channel, which extends vertically. The steel pile can be inserted into the guide channel from the same top and pass through the guide cylinder 2 to sit on the bottom. The guide channel enables the steel pile to sink in a predetermined direction during the pile sinking process to avoid deviation from the target position. At the same time, the guide cylinder 2 can limit the lateral displacement of the steel pile during the pile sinking process, ensure the verticality of the steel pile in the vertical direction, and prevent construction errors caused by lateral movement of the steel pile.

[0064] The main structure 1 is a four-legged jacket frame type, with a number of legs 11 arranged at the vertices of a square. The legs 11 extend vertically to directly or indirectly press against the seabed to support the entire structure of the pile sinking positioning frame. It is understandable that the legs 11 can also be provided with anti-sinking plates 6, operating decks, auxiliary piles and pile punching systems, etc., which can be adjusted by technicians in this field as needed. In addition, the main structure 1 also includes several layers of cross braces 12 and diagonal braces. The main structure 1 is a frame structure composed of legs 11, cross braces 12 and diagonal braces. The anti-sinking plate 6 is a flat plate foundation composed of a Chinese character "Yu" (horizontal) and a beam. The operating deck is located above the water surface to provide an operating space for operators. The auxiliary piles are round steel piles. When in use, they are driven into the mud surface along the main legs of the main structure, and are connected to the main structure through a fixed structure, and are jointly loaded with the anti-sinking plate 6. The pile punching system consists of a main line and a branch line. The pile punching system can eliminate the overburden on the top surface of the anti-sinking plate 6 and the adsorption force at the bottom, thereby facilitating the displacement of the positioning frame.

[0065] In this embodiment, by improving the structures of the support structure 3 and the guide cylinder 2, the pile positioning frame structure in this embodiment can adjust the pile spacing between certain point values. In the example shown in the figure, the pile spacing can be adjusted within the point value range of 32m-36m, and such an adjustment range can cover most pile spacing requirements; those skilled in the art can also change the adjustable range of the pile spacing with reference to the following specific embodiments.

[0066] In this embodiment, the pile driving positioning structure includes a support component group, which is used to support the same guide cylinder 2, and the support component group includes one or more support structures 3 distributed at intervals along the axial direction. When there are two or more support structures 3, the support assembly 30 can form at least two support positions for the guide cylinder 2 in the height direction, thereby improving the support strength of the guide cylinder 2.

[0067] The specific structure of the support structure 3 is described in detail below. The support structure 3 encloses and defines at least one adjustment channel 5, which vertically penetrates the support structure 3 to be inserted into the guide cylinder 2 and is connected to the guide cylinder 2. The adjustment channel 5 has a channel centerline s1 that coincides with the extension of the diagonal of the square. The direction of the adjustment channel 5 perpendicular to the extension of the diagonal of the square in the horizontal plane is defined as the width direction of the adjustment channel 5, and the direction that coincides with the diagonal is the length direction of the adjustment channel 5. The channel centerline s1 extends in the horizontal direction and passes through the midpoint of the width direction of the adjustment channel 5. The horizontal cross-section of the adjustment channel 5 is a rectangle or an isosceles trapezoid.

[0068] Along the extension direction of the channel centerline s1, the adjustment channel 5 is provided with a plurality of installation positions, and the plurality of installation positions correspond to the adjustment point values ​​of different pile spacings. The guide cylinder 2 can be connected to the corresponding different installation positions, and the center of the guide cylinder 2 is always located at the adjustment centerline. The guide cylinder 2 has different structural forms. The center of the guide cylinder 2 here refers to the center of the concentrically arranged part of the guide cylinder 2 to be guided. In the example shown in the figure, the guide cylinder 2 includes a cylinder body 22 and a bell mouth 23 arranged on the cylinder body 22, and the bell mouth 23 is an eccentric structure. In the example shown in the figure, the center of the guide cylinder 2 refers to the center of the cylinder body 22 in the horizontal section.

[0069] By adopting the technical solution of the present application, a pile positioning frame suitable for adjustable pile spacing is provided, and the spacing of the guide cylinder 2 can be adjusted according to the change of the pile spacing of the steel piles of the conductor frame, so that one pile positioning frame structure can be suitable for a variety of pile spacings, thereby improving the scope of use of the pile positioning frame structure and saving the cost of project construction equipment.

[0070] In a specific embodiment, each support structure 3 includes two support beams 31, and the support beams 31 can be box beams, so as to ensure the structural strength of the support beams 31. An adjustment channel 5 is defined between the two support beams 31, and each support beam 31 is arranged parallel to the channel center line s1, that is, the support beam 31 and the channel center line s1 extend in the same direction. A plurality of position limiting teeth 332 are arranged in sequence and spaced apart in the extending direction of the support beams 31 to define different installation positions.

[0071] The outer wall of the guide cylinder 2 corresponding to the limiting teeth 332 is provided with a plurality of protrusions 21 . The protrusions 21 can be inserted between two adjacent limiting teeth 332 on the corresponding side and directly or indirectly pressed against the support beam 31 .

[0072] It is understandable that the adjustment channel 5 can be defined by a plate-like member in addition to being defined by the support beam 31. The plate-like member is arranged perpendicular to the main structure 1, and the adjustment channel 5 vertically penetrates the plate-like member to form a waist-shaped adjustment channel 5. In addition, in addition to the plug-in connection between the protrusion 21 and the limiting tooth 332, other detachable connection methods such as snap connection can also be used.

[0073] The limiting teeth 332 extend in the vertical direction, and a spacing portion 333 is defined between the two limiting teeth 332. In the process of inserting the protrusion 21 into the spacing portion 333, a lifting device is first used to insert the guide cylinder 2 from the outer side of the support beam 31 to the position between the two support beams 31 along the diagonal direction. During the insertion process, ensure that the height of the protrusion 21 is higher than the highest position of the limiting teeth 332; then, after the protrusion 21 is vertically aligned with the corresponding spacing portion 333, the guide cylinder 2 is lowered using a lifting device to insert the protrusion 21 from top to bottom into the spacing portion 333.

[0074] Optionally, in order to facilitate plug-in, the mouth of the protrusion 21 inserted into the spacer 333 is defined as a socket, and the top of the limiting tooth 332 surrounding the socket is provided with a chamfer 3322, so that the spacer 333 has a flared structure.

[0075] In this embodiment, the center position between two adjacent limiting teeth 332 is an installation position, and those skilled in the art can adjust the spacing between each installation position by adjusting the center position between the two limiting teeth 332 as needed.

[0076] In this embodiment, by providing a plurality of spaced-apart limiting teeth 332 on the support beam 31, a plurality of optional installation positions are provided for the guide cylinder 2, thereby allowing the user to easily adjust the position of the guide cylinder 2 according to specific needs to adapt to different pile spacings, thereby greatly improving the flexibility and adaptability of the pile positioning frame; in addition, the protrusion 21 provided on the outer wall of the guide cylinder 2 enables the guide cylinder 2 to be firmly inserted and locked between two adjacent limiting teeth 332 on the corresponding side, directly or indirectly pressed against the support beam 31, thereby ensuring the stability and accuracy of the guide cylinder 2 after adjustment.

[0077] In an optional embodiment, two cam groups 20 are fixedly provided on the side wall of the guide cylinder 2 in the same horizontal plane, and the two cam groups 20 are symmetrically arranged relative to the channel center line s1 to match the corresponding side support beam 31; that is, the two cam groups 20 are opposite in the width direction of the adjustment channel 5. The direction perpendicular to the channel center line s1 is defined as the width direction of the adjustment channel 5; each cam group 20 includes one convex block 21 or two convex blocks 21, and the guide cylinder 2 is defined to have a reference line in the horizontal plane, which passes through the center of the guide cylinder 2 and is perpendicular to the channel center line s1.

[0078] For example, the square main structure 1 includes a first diagonal line and a second diagonal line, and the adjustment channel 5 arranged on the first diagonal line has a width direction, and the width direction of the adjustment channel 5 is perpendicular to the channel center line s1 and parallel to the second diagonal line. The reference line extends along the width direction of the adjustment channel 5. The two protrusions 21 located in the same convex group 20 are symmetrically arranged relative to the reference line. When a protrusion 21 is provided, the two protrusions 21 located at the same elevation are symmetrically arranged relative to the channel center line s1, and are arranged radially opposite to the guide cylinder 2. In this embodiment, the protrusion 21 can be a solid box-type structure or a hollow box-type structure.

[0079] Optionally, in a horizontal plane, a direction perpendicular to the channel center line s1 is defined as the width direction of the adjustment channel 5; in the width direction, the protrusion 21 exceeds the tooth outer side wall 3321 of the limiting tooth 332, that is, in the extension direction of the reference line, the protrusion 21 passes through the spacer 333 and is located on the side of the limiting tooth 332 away from the guide cylinder 2. The protrusion 21 is also provided with a first limiting plate 211, which is provided on both sides of the protrusion 21 and is used to abut against the tooth outer side wall 3321 of the limiting tooth 332 on the corresponding side in the width direction of the adjustment channel 5.

[0080] The first limit plate 211 is a plate-like structure. In the example shown in the figure, the first limit plate 211 is a triangular plate, and the side wall of the first limit plate 211 is fixedly connected to the part of the protrusion 21 located outside the limit tooth 332. Specifically, the two side walls of the protrusion 21 in the extension direction of the channel centerline s1 are fixedly connected with the first limit plate 211. The first limit plate 211 is a right-angled plate. One right-angled side of the first limit plate 211 is fixedly connected to one side wall of the protrusion 21, and the other right-angled side is directly or indirectly connected to the support arm beam. The support beam 31 has a beam top surface 312 extending horizontally. The beam top surface 312 extends in the same direction as the other right-angled side of the first limit plate 211, and forms a direct or indirect abutment vertically.

[0081] The limiting tooth 332 has an inner tooth wall and an outer tooth wall 3321 that are relatively arranged in the width direction, where "inside" and "outside" are defined with reference to the channel center line s1 of the adjustment channel 5. In the width direction, the surface of the limiting tooth 332 that is closer to the channel center line s1 is the inner tooth wall, and the surface that is farther away from the channel center line s1 is the outer tooth wall 3321.

[0082] During the specific assembly process, when inserting the protrusion 21 from top to bottom into the spacer 333, it is necessary to align the first limiting plate 211 with the outer tooth wall 3321 of the limiting tooth 332 vertically, and then use a lifting device to insert the protrusion 21 into the spacer 333.

[0083] In this embodiment, two cam groups 20 are fixed on the side wall of the guide cylinder 2 in the same horizontal plane. The two cam groups 20 are located at the same elevation and are symmetrically arranged relative to the center line s1 of the channel. This design ensures that the guide cylinder 2 can be evenly stressed after adjusting the spacing, and effectively prevents deviation or tilting caused by uneven force on one side.

[0084] At the same time, each cam group 20 includes one or two convex blocks 21, which can be accurately inserted between the limiting teeth 332 of the corresponding side support beam 31 to achieve stable locking. In particular, when the two convex blocks 21 of the same cam group 20 are symmetrically arranged relative to a reference line passing through the center of the guide cylinder 2, the stability of the guide cylinder 2 in the horizontal plane is further enhanced, and the positioning accuracy is improved. The symmetrical distribution of the two cam groups 20 allows the guide cylinder 2 to be easily aligned with the limiting teeth 332 of the support beam 31 during installation, without the need for complex adjustment and calibration steps, simplifying the installation process and reducing installation time.

[0085] Optionally, at least one convex block 21 in the same convex group 20 is further provided with a second limiting plate 212 parallel to the first limiting plate 211, the second limiting plate 212 is arranged opposite to the first limiting plate 211 in the width direction, and can abut against the inner side wall of the limiting tooth 332. The spacing between the first limiting plate 211 and the second limiting plate 212 is adapted to the size of the limiting tooth 332 in the width direction of the adjustment channel 5.

[0086] In the extension direction of the support beam 31, second limit plates 212 are arranged on both sides of the two protrusions 21 located in the same protrusion group 20, one second limit plate 212 is arranged on the side of the two protrusions 21 away from each other, and the second limit plate 212 is follow-shaped with the first limit plate 211, and the other second limit plate 212 is arranged on the side of the two protrusions 21 close to each other, and the second limit plates 212 are connected to each other into an integrated structure.

[0087] In the example shown in the figure, the second limit plate 212 is a rectangular plate, and the two ends of the rectangular plate are respectively fixedly connected to the corresponding side of the protrusion 21. By arranging the second limit plate 212 on the protrusion 21, the first limit plate 211 and the second limit plate 212 can form a stop for the limit tooth 332 on both sides of the limit tooth 332, thus increasing the support of the limit tooth 332 on the guide cylinder 2, and further increasing the stability of the guide cylinder 2 in the process of guiding the steel pile.

[0088] Optionally, a spacer 333 is defined between two adjacent limiting teeth 332, and two cams located in the same cam group 20 are correspondingly adapted to two non-adjacent spacers 333; the first limiting plate 211 exceeds the limiting teeth 332 in the extension direction of the support beam 31. In this way, the first limiting plate 211 can exceed the limiting teeth 332 in the extension direction of the channel center line s1, thereby forming a more stable width direction limit with the limiting teeth 332.

[0089] At the same time, in order to avoid interference between the first limiting plates 211 of two adjacent protrusions 21, the two protrusions 21 are inserted into two non-adjacent spacers 333. Here, the two non-adjacent spacers 333 may be separated by one spacer 333 or two or more spacers 333, and those skilled in the art may choose by themselves. Considering weight reduction and cost reduction, preferably, there is one spacer 333 between the two spacers 333 inserted into the protrusion 21.

[0090] In another optional embodiment, a connecting plate 334 is further included, a portion of the connecting plate 334 is welded to the end face of the protrusion 21, and another portion is welded to the support beam 31. The connecting plate 334 is also a right-angled plate, one right-angled side of the connecting plate 334 is welded to the end face of the protrusion 21, and optionally, is welded to the middle of the end face of the protrusion 21 to obtain better support, and the other right-angled side is welded to the beam top face 312, and the oblique side is supported between the end face of the protrusion 21 and the beam top face 312.

[0091] By setting the connecting plate 334, the guide cylinder 2 and the support beam 31 can be connected vertically, thereby preventing the guide cylinder 2 and the support beam 31 from accidentally disengaging vertically. In actual operation, if it is necessary to adjust the installation position of the guide cylinder 2, the connecting plate 334 can be cut off and re-welded at the new installation position. This processing method is relatively simple and convenient, and can also ensure the vertical connection strength between the guide cylinder 2 and the support beam 31.

[0092] In other embodiments, the pile driving positioning frame includes a limit module 330, which is welded to the top surface of the support beam 31. The limit module 330 includes the aforementioned limit teeth 332 and a support frame 331. The bottom end of the support frame 331 is welded to the top surface 312 of the beam, and several limit teeth 332 located on the same support beam 31 are all welded to the top of the support frame 331.

[0093] During the welding process, the support frame 331 and the corresponding limiting teeth 332 are positioned and matched, and then the limiting teeth 332 are welded to form the limiting module 330. Then the support frame 331 and the support beam 31 are positioned and matched and then welded. In this welding method, it is only necessary to position and weld the limiting teeth 332 and the support frame 331, and then combine and weld the limiting module 330 and the support beam 31.

[0094] Therefore, the position-limiting teeth 332 can be processed in a modular manner, thereby ensuring the position-limiting accuracy of the position-limiting teeth 332 and reducing the difficulty of connecting the position-limiting teeth 332 and the support beam 31 .

[0095] In this embodiment, in order to simplify the positioning of the support beam 31 and the support frame 331 in the width direction, the support beam 31 also includes a beam inner side wall 311, which is arranged perpendicular to the beam top surface 312, and the beam inner side wall 311 constitutes the wall portion of the adjustment channel 5. The "inside" here means that in the width direction, the support beam 31 is closer to the channel center line s1, and the beam inner side wall 311 is welded perpendicular to the beam top surface 312.

[0096] The support frame 331 includes a horizontal plate 3111 arranged parallel to the beam top surface 312 and two vertical plates 3112 perpendicular to the beam top surface 312. The vertical plates 3112 extend in the same direction as the support beam 31 and are arranged opposite to each other in the width direction. The horizontal plate 3111 is fixedly connected to the top of the vertical plates 3112.

[0097] The support frame 331 has a stop surface 3114, which extends vertically and is located in the same plane as the inner side wall 311 of the beam. In the width direction, both sides of the horizontal plate 3111 extend beyond the outside of the vertical plate 3112, and the stop surface 3114 is located at the inner side wall 3111a of the horizontal plate 3111. In the width direction, that is, in the extension direction of the reference line, the side of the horizontal plate 3111 closer to the guide cylinder 2 is the inner side, and the opposite side is the outer side.

[0098] In this way, after the support frame 331 is welded to the beam top surface 312 of the support beam 31, the horizontal plate 3111, the vertical plate 3112 and the beam top surface 312 form an I-beam structure. The number of vertical plates 3112 can be two or one, and the two vertical plates 3112 are arranged opposite to each other in the width direction. In this way, the side wall of the guide cylinder 2 can be limited, and the welding of the module and the welding positioning are convenient.

[0099] The support frame 331 is composed of a horizontal plate 3111 arranged parallel to the beam top surface 312 and two vertical plates 3112 perpendicular to the beam top surface 312. This design enables the support frame 331 to fit more firmly on the beam structure, effectively disperse and withstand loads from above or from the side, and improve the stability and bearing capacity of the overall structure.

[0100] The stop surface 3114 may be located on the inner side wall of the horizontal plate 3111 or on the inner wall of the vertical plate 3112 , and can be adjusted by those skilled in the art.

[0101] In another optional embodiment, a welding plate 3113 is further provided between the beam top surface 312 and the horizontal plate 3111 . The welding plate 3113 is parallel to the vertical plate 3112 and is located on the outside of the vertical plate 3112 . Part of the connecting plate 334 is welded to the outer side wall of the welding plate 3113 .

[0102] In the example shown in the figure, two vertical plates 3112 are included, and the welding plate 3113 is arranged on the side of the outer vertical plate 3112 away from the inner vertical plate 3112, and is arranged spaced apart from the outer vertical plate 3112 in the width direction. The outer plate wall of the welding plate 3113 refers to the surface of the welding plate 3113 on the side away from the vertical plate 3112. The method of separately arranging the welding plate 3113 on the outer side of the position parallel to the vertical plate 3112 facilitates the welding of the connecting plate 334 and the supporting frame 331, while preventing the connecting plate 334 from being directly welded to the vertical plate 3112, which causes stress concentration on the part of the vertical plate 3112.

[0103] In this embodiment, the outer side of the horizontal plate 3111 exceeds the welding plate 3113, and the horizontal plate 3111 extends in the width direction, and both sides of the horizontal plate 3111 in the width direction exceed the vertical plate 3112, and the outer side of the horizontal plate 3111 exceeds the welding plate 3113. However, the outer side of the horizontal plate 3111 is spaced from the outer edge of the beam top surface 312, and the space is used to weld the connecting plate 334. The size of the space in the width direction is greater than the size of the horizontal plate 3111 in the width direction. The ratio is greater than 1:2, thereby reserving sufficient welding space for the connecting plate 334, ensuring the welding strength of the connecting plate 334 and the beam top surface 312.

[0104] At least part of the connecting plate 334 is supported between the lower plate wall of the horizontal plate 3111 and the beam top surface 312. By extending the connecting plate 334 to the lower side of the horizontal plate 3111 and welding it to the lower plate wall of the horizontal plate 3111, the support frame 331 can further limit the connecting plate 334 in the height direction, further improving the connection strength of the guide cylinder 2 and the support beam 31 in the vertical direction.

[0105] Optionally, a spacer 333 is defined between two adjacent limiting teeth 332; and a reinforcing rib plate 3115 is also included. The reinforcing rib plate 3115 is perpendicular to the vertical plate 3112 and connected between the beam top surface 312 and the lower plate wall. The reinforcing rib plate 3115 is also a right-angle plate, one right-angle side of which is welded to the vertical plate 3112, the other right-angle side is welded to the beam top surface 312, and the hypotenuse is against between the vertical plate 3112 and the beam top surface 312. The reinforcing rib plates 3115 are spaced apart along the extension direction of the channel center line s1, and the size of the limiting teeth 332 in the extension direction of the channel center line s1 is adapted to the size between the two reinforcing rib plates 3115.

[0106] The reinforcing rib plate 3115 is projected vertically to form a first projection, the spacer 333 is projected to form a second projection, the limit tooth 332 is projected to form a third projection, and the welding plate 3113 is projected to form a fourth projection; the first projection at least partially overlaps with the third projection, and the first projection is aligned with one side of the third projection, or is aligned with the other side of the third projection in the direction of the channel centerline s1, the third projection at least partially overlaps with the fourth projection, and in the direction of the channel centerline s1, the sizes of the third projection and the fourth projection are adapted to each other.

[0107] The limiting teeth 332 are spaced apart from the inner side wall 3111a and the outer side wall of the transverse plate 3111 in the width direction; the right-angle edge of the connecting plate 334 is pressed against the transverse plate 3111 , thereby forming an indirect connection with the support beam 31 .

[0108] In this way, the reinforcing rib plate 3115 further strengthens the part where the limiting teeth 332 are set, thereby increasing the connection strength between the limiting teeth 332 and the support beam 31; at the same time, the welding plate 3113 further strengthens the spacer portion 333 where the protrusion 21 is set; after the protrusion 21 is connected to the support beam 31, the connecting plate 334 is parallel to each reinforcing rib, which can also further improve the connection strength between the protrusion 21 and the support beam 31.

[0109] In other embodiments, the guide cylinder 2 includes a cylinder body 22 and a bell mouth 23 disposed on the cylinder body 22, the bell mouth 23 having a large diameter end and a small diameter end, the bell mouth 23 is vertically connected to the upper side of the cylinder body 22, and the cylinder body 22 is connected to its small diameter end. Two cam groups 20 located in the same plane are disposed at the position where the cylinder body 22 and the bell mouth 23 are connected.

[0110] A first reinforcing plate 231 is also provided, part of which is fixed to the outer wall of the bell mouth 23, and part of which is fixed to the upper surface of the protrusion 21. The first reinforcing plate 231 and the welding plate 3113 are located in the same plane in the vertical direction. In this embodiment, the first reinforcing plate 231 is located in the middle of the protrusion 21, that is, in the middle of the spacer 333.

[0111] In the horizontal direction, the wall of the bell mouth 23 is in an inclined state, that is, it gradually inclines outward from the low point where the tube body 22 is located to the high point. In the vertical direction, the bell mouth 23 and the protrusion 21 are projected respectively, and the projection range of the bell mouth 23 will cover the projection range of the protrusion 21. By connecting the upper surface of the protrusion 21 with the outer wall of the bell mouth 23 through the first reinforcing plate 231, the connection part between the protrusion 21 and the guide tube 2 can be further strengthened.

[0112] In other embodiments of the present application, in order to achieve a fixed connection between the support beam 31 and the main structure 1, the support structure 3 further includes a transition portion 4, which is integrally formed with the support beam 31 and is an integral structure. The support beam 31 is fixed to the transition portion 4, which is sleeved on the outside of the support leg 11 and fixedly connected to the support leg 11. The support structure 3 is integrally connected to the support leg 11 by the transition portion 4, thereby improving the reliability of the connection between the support structure 3 and the main structure 1.

[0113] The main structure 1 further includes a cross brace 12 connected between two adjacent legs 11; the cross brace 12 is welded to the portion of the leg 11 provided with the adapter 4. By also providing the cross brace 12 at the portion where the adapter 4 and the leg 11 are connected, the portion of the leg 11 connected with the adapter 4 is further reinforced by the cross brace 12 to prevent the leg 11 from buckling. Optionally, the portion of the leg 11 connected with the adapter 4 is also fixedly connected to a diagonal brace, so that the corresponding position of the leg 11 can be further reinforced.

[0114] In an optional embodiment, a first reinforcing beam 13 is further included, one end of the first reinforcing beam 13 is welded to the transition portion 4, and the other end is welded to the cross brace 12; the first reinforcing beam 13 and the cross brace 12 are located in the same plane. Thus, the cross beam is further reinforced by the first reinforcing beam 13, and the connection strength between the transition portion 4 and the cross brace 12 is increased.

[0115] Optionally, a second reinforcing beam 14 is further included, and the second reinforcing beam 14 is connected between two adjacent cross braces 12, and the second reinforcing beam 14, the first reinforcing beam 13, and the cross brace 12 are located in the same plane. Thus, the horizontal support of the cross beam to the support leg 11 can be further improved.

[0116] Furthermore, the adapter 4 includes a first beam 41, a second beam 42, and a connection end 43 for fixedly connecting to the support leg 11; one end of the first beam 41 and the second beam 42 are fixed to the connection end 43, and the other ends extend in a direction away from each other and are fixedly connected to the support beam 31 on the corresponding side. By providing the adapter 4, the two support beams 31 can be fixedly connected to the vertically extending support leg 11, thereby realizing a rigid connection between the support beam 31 and the main structure 1.

[0117] In the above embodiment, the adapter 4 further includes a reinforcing block 44, which is abutted between the first beam 41 and the second beam 42, and is connected to the connection end 43, a part of the inner wall of the first beam 41, and a part of the outer wall of the second beam 42; the reinforcing block 44, the two first reinforcing beams 13, and the second reinforcing beam 14 form a closed structure, thereby further forming a stable support for the adapter 4 in the horizontal direction.

[0118] In the above embodiment, the support component group further includes an x-shaped support frame 32, which is disposed between two adjacent support structures 3; the top end of the x-shaped support frame 32 is fixedly connected to one of the two support beams 31 located on the same side of the two support structures 3, and the bottom end is fixedly connected to the other. Thus, the two support beams 31 in the height direction can be further supported by the x-shaped support frame 32, thereby improving the support capacity of the support assembly 30 for the guide cylinder 2 in the height direction.

[0119] Specifically, the top end of the x-shaped bracket 32 ​​is fixed to the lower surface of the support beam 31 located on the upper side, and the bottom end is fixed to the beam top surface 312 of the support beam 31 located on the lower side. In order to support the x-shaped bracket 32, the beam top surface 312 of the support beam 31 extends outwardly to form an upper mounting plate, which extends horizontally, and a portion of the lower surface of the support beam 31 is pressed against the beam top surface 312, and a portion is pressed against the upper mounting plate. A support plate is also provided between the upper mounting plate and the outer side wall of the support beam 31, and the support plate is used to support the upper mounting plate.

[0120] Similarly, a lower mounting plate is also provided on the lower surface of the support beam 31, and the lower mounting plate extends in the horizontal direction and matches with the upper mounting plate. The top portion of the x-shaped support frame 32 is fixedly connected to the lower mounting plate, and the other portion is fixedly connected to the lower surface of the support beam 31. Of course, the support beam 31 may also protrude outward to form a boss, and the boss is used to fix the x-shaped support beam.

[0121] By adopting the technical solution of the present application, the guide tube 2 can achieve five different spacings of 32m, 33m, 34m, 35m and 36m, thereby adapting to different jacket pile spacings.

[0122] When the spacing of the guide cylinders 2 needs to be adjusted, the connecting plate 334 between the guide cylinder 2 and the support beam 31 is cut off, the guide cylinder 2 is lifted off the spacing portion 333 of the support beam 31, and then it is moved into the spacing portion 333 of the target spacing, and then the guide cylinder 2 and the support beam 31 are fixed by the connecting plate 334, so that the spacing of the guide cylinder 2 is adjusted. If the pile diameters of different jackets vary, after removing the guide cylinder 2, the guide cylinder 2 can be lifted to the deck of the work ship, the radioactive limit ribs in the guide cylinder 2 can be adjusted, and then the guide cylinder 2 can be installed and fixed in the spacing portion 333 of the corresponding spacing of the support beam 31, so that the applicable pile diameter can be adjusted.

[0123] Compared with the prior art, this application has the following advantages:

[0124] First, the design of the adjustment channel 5 enables the guide cylinder 2 to move therein and maintain a set position to adapt to different pile spacings.

[0125] Second, the guide cylinder 2 is connected to the support beam 31 through the protrusion 21 and the connecting plate 334, which facilitates the connection and removal of the guide cylinder 2 and the adjustment channel 5.

[0126] Thirdly, the design of the sawtooth limit module 330 can enable the guide tube 2 to accurately realize the switching adjustment of different spacings by installing the protrusions 21 of the guide tube 2 in different spacing parts 333, so that the same pile positioning frame structure can be applied to various pipe frame pile spacings.

[0127] Fourthly, the design of the detachable guide tube 2 facilitates the placement of the guide tube 2 on the deck of the construction vessel, and the adjustment of the radial limiting ribs in the guide tube 2 can be performed at the construction site, thereby realizing that the same guide tube 2 can adapt to the changes in different jacket pile diameters at a low cost.

[0128] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
